System realization System realization activities are conducted to create and test versions of a system as specified by system definition system definition.
These activities include those required to build a system system implementation system implementation , integrate disparate system elements system integration system integration , and ensure that the system meets both the needs of stakeholders system validation system validation and aligns with the system requirements and architecture system verification system verification.
These activities are not sequential, but are performed concurrently, iteratively and recursively depending on the selected life cycle model. Figure 1 see "Overview", below , also shows how these processes fit within the context of system definition system definition and System Deployment and Use KAs.
See also Applying Life Cycle Processes for further discussion of the relationships between process and life cycle model. The KAs in turn are divided into topics. This KA contains the following topics:. See the article Matrix of Implementation Examples for a mapping of case studies and vignettes included in Part 7 to topics covered in Part 3.
Essentially, the outputs of system definition system definition are used during system implementation system implementation to create system elements system elements and during system integration system integration to provide plans and criteria for combining these elements. The requirements are used to verify verify and validate validate system elements, systems, and the overall system-of-interest system-of-interest SoI. These activities provide feedback into the system design, particularly when problems or challenges are identified.
Finally, when the system is considered, verified, and validated, it will then become an input to system deployment and use. It is important to understand that there is overlap in these activities; they do not have to occur in sequence as demonstrated in Figure 1. Every life cycle model includes realization activities, principally, verification and validation activities.
The way these activities are performed is dependent upon the life cycle model in use. Figure 2 illustrates a macro view of generic outputs from realization activities when using a Vee life cycle model.
The left side of the Vee represents various design activities 'going down' the system. The left side of the Vee model demonstrates the development of system elements specifications and design descriptions. In this stage, verification and validation plans are developed, which are later used to determine whether realized system elements products products , services services , or enterprises enterprises are compliant with specifications and stakeholder requirements stakeholder requirements.
Also, during this stage initial specifications become flow-down requirements for lower-level system models. These activities are discussed further in the System Definition KA. However, it is important to understand that some of the system realization activities are initiated at the same time as system definition activities; this is the case with integration, verification and validation planning in particular.
The right side of the Vee model, as illustrated in Figure 2, shows the system elements products, services, or enterprises are assembled according to the system model described on the left side of the Vee integration. Verification and validation activities determine how well the realized system fulfills the stakeholder requirements, the system requirements, and design properties design properties.
These activities should follow the plans developed on the left side of the Vee. For example, integration typically starts at the bottom of the Vee and continues upwards to the top of the Vee.
The U. To implement a program is to translate a more or less detailed design into code, not to translate some vague idea into code. In other words, the idea for the product is realized by specifying it, capturing a design at various levels of detail and finally implementing it.
Programmers also speak of implementing specifications. Basically, any document that gives precise, testable requirements for the external behavior of a data processing system is susceptible to being implemented. We speak of the duality of interface how the world communicates with some piece vs. Realize can also have the more direct sense of "make real," and is often used and sometimes overused; your first sentence probably should use "implement" to avoid sounding self-important in this sense in technical literature.
Now that someone downvoted, let me show evidence: Wikipedia: Implementation :. Implementation is the realization of an application, or execution of a plan, idea, model, design, specification, standard, algorithm, or policy. Wikipedia: Instruction set architecture :.

I don't agree with the first part of your "To implement a program is to translate a more or less detailed design into code, not to translate some vague idea into code.
But implementing the program would mean that the finished version is made live and put into action. The program could be fully finished but never implemented. I was thinking of situations, for example, where a perfectly workable program had been written but the company changed its mind about what functionality it wanted, and decided on a different strategy, therefore leaving the program to metaphorically gather dust on the shelf instead of implementing it.
The deploy or put into effect meaning of implement is not relevant in this question; it is about the development of the program code. Kaz: So, if I understand you correctly, the two examples in my question are incorrect or odd usages of to realize in your opinion? Or would you consider one of them to be fine? Show 2 more comments.
